Today we got episode focused on Ruby and B komachi 2.0. I really enjoy that the characters aren't just AI with puppets but actual human being with emotions and variable amount of EQ. The love is romance is braving underneath and every character has different emotional response.

A lot of musical bits were included in the episode:

A training montage:
Girls training

A comedy bit:
Kana in pepper costume

And an clip from music video:
Kana with the moon

I am not the huge fan of musicals but as a plot device it was really cool. In the background we see Aqua scheming, captivating and making strong connections.
